Specific Heat Capacity Flashcards
1
Q
What is specific heat capacity?
A
The energy needed to raise the temperature of1kg of a substance by 1 degree.
2
Q
What is the equation for specific heat capacity?
A
E = m × c × θ E is energy transferred, J m is mass, kg c is specific heat capacity, J/kg°C θ is temperature change
3
Q
Is it quicker or slower heat up an object with a great
mass?
A
It is take longer to heat up an object with a greater mass.
4
Q
what is the unit of specific heat capacity?
A
J/kg°C
5
Q
The specific heat capacity of water is 4200J/kg°C. how much energy is needed to raise the temperature of 2kg of water by 1 °C?
A
E=2 x 4200 x 1
8400J
